Large-scale phase retrieval. [PDF]
Light Sci Appl, 2021 High-throughput computational imaging requires efficient processing algorithms to retrieve multi-dimensional and multi-scale information. In computational phase imaging, phase retrieval (PR) is required to reconstruct both amplitude and phase in complex ...

Phase Retrieval with Random Phase Illumination [PDF]
Journal of the Optical Society of America A, 2012 This paper presents a detailed, numerical study on the performance of the standard phasing algorithms with random phase illumination (RPI). Phasing with high resolution RPI and the oversampling ratio $\sigma=4$ determines a unique phasing solution up to ...

PhaseLin: Linear Phase Retrieval [PDF]
2018 52nd Annual Conference on Information Sciences and Systems (CISS), 2018 Phase retrieval deals with the recovery of complex- or real-valued signals from magnitude measurements. As shown recently, the method PhaseMax enables phase retrieval via convex optimization and without lifting the problem to a higher dimension.

Undersampled Phase Retrieval with Outliers [PDF]
IEEE Transactions on Computational Imaging, 2014 We propose a general framework for reconstructing transform-sparse images from undersampled (squared)-magnitude data corrupted with outliers. This framework is implemented using a multi-layered approach, combining multiple initializations (to address the

Phase retrieval with polarization [PDF]
SIAM Journal on Imaging Sciences, 2013 In many areas of imaging science, it is difficult to measure the phase of linear measurements. As such, one often wishes to reconstruct a signal from intensity measurements, that is, perform phase retrieval.

Phase Retrieval: From Computational Imaging to Machine Learning: A tutorial [PDF]
IEEE Signal Processing Magazine, 2022 Phase retrieval consists in the recovery of a complex-valued signal from intensity-only measurements. As it pervades a broad variety of applications, many researchers have striven to develop phase-retrieval algorithms.

Algebraic theory of phase retrieval [PDF]
Notices of the American Mathematical Society, 2022 The purpose of this article is to discuss recent advances in the growing field of phase retrieval, and to publicize open problems that we believe will be of interest to mathematicians in general, and algebraists in particular.
